Hell worlds also contain seams of Blackrock that can only be removed with Bombs. You can find the same Resources while mining underground, that are found in a Temperate Biome world, with the addition of a few items and unique ore.

Expiator Activation & Use

Once you have found all 7 Expiator Parts, you can then tap on the Expiator itself to activate it. Expiator is a unique machine used to release Lost Souls, it only works specifically with the friendly ghosts (with names).

It is beneficial to mark the location of all 12 Infernal Protecters with Plaques, Teleporters, or Micro Protectors before using the Expiator. This is because finding their location is much easier with obvious purple glow still present.

Benefits of Developed Hell World

After the Expiator is repaired, you are able to use it to release Lost Souls. Each deliverance removes one random Infernal Protector, thus freeing up previously unexplored areas.
